Digital product course lesson videos 2:00 timing?

New to uploading course offerings. All of my short videos in my course chapters and lessons (3-5 minutes each) are now showing only as 2 minutes in the Course Overview time count. Am I doing something wrong?

Should I upload elsewhere (Vimeo) and embed? This just happened, as of 3 days ago, I thought (?) the time stamps were correct.

Do I really have to reupload all of these videos??? 😞 

I wanted to give an update. If I turn on the "show video" full screen option in the course, the time is correct. If I embed from Vimeo as code or link, or Squarespace video block, it shows as 2:00. The video plays in entirety, but the time is still wrong and shows as 2:00. Is this a default setting, or can I manually change somehow.

Any tips?
